A few weeks ago i had a coil pack go on my car and had to be recovered. I had the coil pack replaced but since my car asn't run properly. The mechanic say the air value was worn and not working properly so i had it replaced. Now it running a bit better but still not right. It judders as you accelerate and looses power on the pull of. If i paid to have it put on a diagnostic machine, would it tell me exactly whats wrong with the car ?

[:)] It might if it is put on a main dealers main frame diagnostics, and your car has an on board computer, but "It judders as you accelerate and looses power on the pull of" , this is the usual sign of a worn/contaminated/ damaged Clutch.

i was thinking it was an engine problem as its not running properly and dosen't sound right. I was thinking the problem could be along the fuel side of things and that why i thought of having it diagnostic tested to pin point the fault. How do you know if your car as a computer on board? My car is a 2001 ford focus.

[:)] Take it to a Ford main dealer and get a price for a full Diagnostic engine check, if you had the air valve replaced, and it is still not running properley, it could be any number of things, from a simple air leak somewhere, that is throwing the on board engine management system mapping out.
Larry mate I would be very suprised if a 2001 Ford Focus was fitted with contact breaker points.[8D]

I got a fault code reader off ebay for my Golf - only about 40

It has paid for itself several times over - think dealers charge 50 just to connect you to one !

One thing with my car is that the dash warning lights often "share" a range of faults.

The engine management light came on, and I feared the worst..

Connected the code reader and it was the brake light switch which I replaced for a fiver. Could have been well fleeced if I had taken it to the dealer with that light flashing.

That said - I have regular services - so it does get a check over every year by an expert.

ME,i doubt its the clutch,, more likely,to be an engine fault could still be the coil pack,
it may be wrong one ,or could be faulty

at one time a a awfull lot of new cars were off the road, due to faulty coilpacks ,most were made by same manufacturer

Find the ECU plug and disconnect it put a spray of WD 40 into the plug and shake out the excess plug it back in and fasten the fixing clamp down and give it another try, if that fails have a look under the spare wheel there could be a fuel cut off switch under it that operates the fuel pump should be coloured red, the old escorts used to have one there. Also check the oil level as if this is low it will put the ECU into limp home mode

It could be a MAF fault (Mass Air Flow Meter), I don't know for sure that your car has one but I know that a lot of cars (especially VW's) suffer from dodgy MAF's a lot of the time!

The things your describing sound indicative of a dodgy MAF.
